San Francisco bar issues passive aggressive Google Glass ban

SAN FRANCISCO drinkers have been subtly told by a trendy bar that Google Glass is not welcome in their establishment.

Gastropub The Willows was visited by a Google Glass Explorer and shortly after a notice appeared advising customers: "Our patrons have expressed concern with being recorded while enjoying themselves at The Willows. Kindly remove before entering."

Although the sign does not mention Glass by name, the sign is illustrated with a crossed out Google Glass.

Another bar in the area, Molotovs, has its own sign forbidding audio and video recording, following a reported assault, during which Glass Explorer Sarah Slocum's computer display eyewear apparently was snatched from her face, along with her purse and mobile phone.

Ms Slocum alleged that the attack took place as a result of customer fears about being recorded by the device.

Issues surrounding the wearable technology are causing problems for the 30,000 Google Glass Explorers - the company's term for beta testers - ahead of the launch of Glass that Google is expected to announce later this year.
